5.2.7 The correct way to overcome obstacles
CAUTION: If the lifter is raised, the drive wheels can lose ground contact when
descending from obstacles or driving on an uneven surface! The "Stability Lock"
prevents “Walking Beam“ spring deflection when the lifter is raised!
•
Never descend from obstacles when the lifter is raised or drive on an uneven surface!
•
In the event of the drive wheels losing ground contact, the lifter must be lowered so that the
drive wheels come into contact with the ground again.
Ascending and descending
The same approach applies to both ascending and descending obstacles:
•
Approach the obstacle or the kerb slowly and at a right angle.
•
Stop shortly before the front wheels come into contact with the obstacle.
•
Check the position of the front wheels. They must be in driving direction
and vertical to the obstacle!
•
Approach slowly and keep at a consistent speed until the rear wheels
have also passed over the obstacle.
